In thinking about The Hobbit, now that each Dwarf is differentiated from eachother, I wonder how they will function within the story.

Ori for example, seems like the bookish younger brother, will that come out in Rivendell at all? Will he be one of the first ones trying to help Bilbo with the side door outside The Lonely Mountain? Will Ori be a source of Dwarven knowledge maybe in culture or language? He looks like a monk after all. "The world is indeed full of peril, and in it there are many dark places; but still there is much that is fair; and though in all lands love is now mingled with grief, it grows perhaps the greater."-J.R.R.
